: Volcanoes may have cooled the Earth by 0.05 ° C to 0.12 ° C since 2000
: The scientists had overlooked the role of aerosols by small eruptions
: Aerosols accumulate between the stratosphere and the troposphere
This layer of the atmosphere is difficult to study how clouds darken
: Eruptions through the 1990s and 2000s contributed to warming ‘pause’
: Global temperatures plateaued since 1998, after a rapid warming in 1990
: The results indicate models that predict climate change should be reviewed
Small volcanic eruptions in the last 20 years have been protecting the earth from global warming, according to a new study.
Scientists have confirmed that the aerosol droplets rich in sulfur spewed into the upper atmosphere by volcanoes were reflecting sunlight away from the Earth.
Until recently it was thought that only very large eruptions had no obvious effect on the climate.
Eruptions of volcanoes as Tavurvur in Papua New Guinea in 2006 have had a greater impact on the climate over the last 15 years that had been previously appreciated and may require climate models to be reviewed
Results, however, the new study confirmed the end of last year showed that these small eruptions can have a cumulative impact of global temperature.
This may have contributed to lower global temperatures of 0.05 ° C to 0.12 ° C over the last 15 years.
